i DUST-PROOF JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 775,566, dated November 22, 1904.

Application filed August 2, 1904.

To all whom, it may concern:

Be it known that I. JAMES A. KENNEDY. a citizen of the United States, residing at Kansas City, in the county of Wyandotte and State of attachment of the type mentioned which is of simple, durable, and cheap construction and which can be placed in or removed from operative position quickly and easily.

To this end the invention consists in certain novel and peculiar features of construction;v

and organization, as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in which- Figure l is a perspective view of the preferred type of a journal-box with which my dust-proof attachment is associated. Fig. 2 is a central vertical section of the same with the box closed and the attachment in place. Fig. 3 is a detail perspective view of the attachment. Fig. 4: is a side view of a modified form of the same. Fig. 5.is a detail sectional view showing the pivotal connection between the box and door.

In the said drawings, 1 indicates the journal-box, which may be of the type shown or of any other suitable or preferred type. The box has the lower half of its front end in the form of an oil-tank 2, said oil-tank forming the lower side of the opening 3, leading from the front end of the box to its interior. At one side-0f the opening the box is equipped with a perforated ear 4 and at the opposite side with an outwardly-projecting flange 5. Mounted in said ear is a bolt 6, equipped between its head and the rear side of the ear with a helical spring 7 At the opposite side of the ear a nut 8 is mounted on the bolt and is retained in position reliably by a springcotter or linchpin 9.

10 indicates the door of the box, the same Serial No. 219,187. (No model.)

having an ear 11 preferably mounted on bolt 6 between ear 4 and nut 8, the arrangement being such that the door-ear is held with a yielding pressure against the ear 4 for the purpose of compensating for any irregularities in the proximate faces of the end of the box and the door. the door from its ear and at its rear side is formed an angle-flange 12, the same extending concentrically of the pivot-bolt, which is also true of the box-flange 5, so that when the door is manipulated to close the opening of the box said hook-flange shall interlock with flange 5, and to prevent the door swinging downward too far in such movement it is provided with a rearwardly-projecting flange or shoulder 13 to abut and rest against the upper edge of the box. The door near one of its outer cornersnamely, that which is uppermost when the door is closedhas an outwardly-projecting boss l hhaving a passage 15 extending through the door and of reduced diameter at its outer end, as at 16, and

fitting slidingly in said passage is a conicalpointed locking-pin 17, which normally projects through the door and has a reduced stem 18 extending outwardly through the reduced portion 16 of the passage 15, an expansive spring 19 surrounding said stem and bearing at its opposite ends against the boss and the body portion of the locking-pin, so as to hold the latter yieldingly projected through the door. A finger-ring 20, secured to the other end of the stem, limits the inward or rearward movement of said pin and provides means whereby it can be easily and quickly retracted.

21 indicates a tin or other sheet-material dust-guard of size and form to completely bridge the opening 3 and fit snugly and squarely against the front end of the box. The guard is provided with a depressed central portion 22 to project into the box, as shown in Fig. 2, a rearwardly-proj eotin g flange 23 at its upper end to rest upon the upper edge of the box, and a depending flange 24 to extend down into the box beyond the lower margin of opening 3, the last-named flange being adapted to reconduct into the tank any oil which splashes up against said flange and At the opposite end of location of the dust-guard.

which might otherwise work its way through the door opening below the depressed portion of the guard, and the latter is provided at its front side with a handle, as at 25, which is gripped by the operator when placing the guard in or removing it from position.

When the guard is in position, as explained, it will provide a dust-proof connectionthat is. when the door is closed it instead of coming in direct engagement with the front end of the box presses the guard against such end, the spring 7 yielding enough to permit this action to occur, and the pressure is sufficient to flatten the guard against the end of the box. As the door is swung to its closed position the conical or tapered end of the pin 17 comes in contact with the upper end of the guard and is forced outward against the resistance of spring 19, said spring instantly reprojecting said pin, when'th e latter registers with the depressed portion of the guard, the result being the pin presses against the upper wall of said depressed portion, as shown in Fig. 2, and reliably locks the door from moving upward under the jolting action of the car, and thereby guards against any possibility of dis- When the guard is used in connection with an ordinary journal, the rearwardly-projecting flange 23 is dispensed with, and the depending guide flange 24 is by preference narrowed, as shown by the modified form, Fig. 4:. In other respects the guard is applicable to the journal-box now in common use, and in this connection it will be seen that whatever dust passes the door collects in the cavity of the guard and is dislodged by brushing it out or by removing the guard and knocking the dust out.

From the above description it will be apparent that I have produced a journal-box embodying the features of advantage enumerated as desirable in the statement of the object of the invention, and it is to be understood, of course, that the attachment is susceptible of modification in minor particulars without departing from its essential spirit or scope or sacrificing any of the features of advantage of the invention.

Having thus described the invention, what I claim as new. and desire to secure by Letters Patent, is

1. A dust-guard of sheet material adapted to yield under pressure and having a depressed portion inward of its margin and also having a resilient flange depending from the guard in substantially the plane of the base of said depressed portion and extending substantially parallel with the non-depressed portion of the guard, depending at the front edge of the depressed portion.

2. The combination with a journal-box having an opening in its front end, and a door to close said opening, of a guard interposed between the end of the box and said door and provided with adepressed portion projecting into the box through said opening, and also provided with a resilient flange depending within the box and below the plane of the lower margin of said opening.

3. The combination with a journal-box having an opening in its front end, and a door. to close said opening, of a guard interposed between the end of the box and said door and provided with a depressed portion projecting into the box through said opening, and also provided with a resilient flange depending within the box and below the plane of the lower margin of said opening, and means for locking the door in its closed position.

4;. The combination with a journal-box having an opening in its front end, and a door to close said opening, of a guard interposed between the end of the box and said door and provided with a depressed portion projecting into the box through said opening, and also provided with a flange depending within the box and below the plane of the lower margin of-said opening, and a spring-actuated locking-pin carried by the door and adapted to enter the depressed portion of the guard to lock the door in its closed position.

In testimony whereof I aflix my signature in the presence of two witnesses.
